| 摘要 |
The invention relates to a slide fastener comprising two rows of toothed chains (1) and a slide (3) which is provided with a reversible electric motor (11) coupled to a mechanism (9) with a drive shaft (10) connected to at least one toothed or pin wheel (5) which engages between the teeth of one toothed chain (1). The electric motor (11) is attached to a control device (12) with a current source (13). Alternatively, the free ends of the teeth of the toothed chains have slots (15) parallel thereto which extend up to the middle of the coupling zone. A reversible electric motor controlled by a control device with a current source is provided at the end of the slide fastener, is connected to a spool (16) on which a thread (19) is wound which extends through the slots (15) of the teeth and is connected, at the free end, to the slide (3). |
